WTC Building 7, why and how it was demolished..

I believe I figured out why building 7 was knocked down.

From what I have read, WTC 7 housed CIA, Secret Service, FBI and other government offices. In demolition the explosives are mostly wired directly, they rarely use remote controls. Because of safety issues demolition experts rarely use remote controls, especially in an urban enviroment as there are so many radio waves in the air at any given time that an accidental interference could cause the explosives to prematurely detonate.

My theory is that WTC 7 was the "Plunger"

The pre wired explosives were wired from the Twin towers to WTC 7. My theory is that as a safeguard the government along with insurance companies and the owners of the building had a fail safe device implanted into the building after the original bombing back in the 90's. To prevent any uncontrolled collapse of the building in case of a terrorist attack, as WTC was next to so many buildings and a known target for terrorists, they figured it is best to have a plan in case it was bombed again, so they pre wired it to bring it down in case of a terrorist attack. The plunger device was in WTC 7.

That is my theory at least, nothing malicious on behalf of the normal people. The GOV I dont know about, but I believe the regular people just wanted to make sure everything was safe in case of the worse case scenario.

Let me know what you think about this theory.
